The outer shell dous not expand $TARPROG, because of the single
quotes. The inner shell can not expand $TARPROG properly, because it
does not get the right value for it. Passing TARPROG via environment
is a solution. The same solution could be used to avoid breaking the
singlequotes for TEXDIR.

I suggest:
  (
    cd "$CDDIR"
    TARPROG=$TARPROG TEXDIR=$TEXDIR $XARGS \
      sh -c '$TARPROG cf - "$@" | (cd "$TEXDIR"; umask 0; $TARPROG xf -)' sh
  ) <$work_dir/files
